Hi Bep,

nice to hear from you again. About that value (22 kHz) I am not so sure it was the last one found (I am going to re-check my own lenghty documentation)...anyway I do remember that I did an 'inverse' evaluation. I mean that I found the natural 'resonance' of the coil and than...as it was too much high I just resonate it lower by adding a parallel tank cap (...just like dfro suggested!). But I do remember as well that the most important effect found was the use of first & second harmonics that being developed from asyncrhonous sources did indeed auto-align with also the 3rd freq and then sum-up producing in output that beatiful '3 Sisters' almost sinusoidal waveform with lot of power available.

Yes.

The important part for me was realizing we should avoid generating harmonics from each source but have them appear as 'near' harmonics to each other.

And the understanding that magneto acoustic effect does not need to come from a ferrous like core. Having a magnetic field from a conductor can produce the same effects as a ferrous core - only more interesting, faster, and movable.

Hoping to be back at the bench this weekend after a very long trip!

Hello all,

the last few days I was working on a tube power supply like SM told us. Its fine working, bla,bla.... not to bother you.

In short:

when the power supply is switched off I see the electrolytic cap slowly discharging to 0V. Slowly because I dont use a bleeder resistor.

But!!

When the cap is totally discharged it starts again to charge!

So I diconnected to 230V from the wall. Still charging. I disconnected the oscillators. Still charging.

Then I took only the 5U4 tube and connected this cap to the tube and to the ground. No meters, nothing. Just the 5U4 + my cap. This was one of the reasons I bought this tube because the same happens with my EZ 81 tube.

After 20 hours I measured 10V on the electrolytic cap.

The setup is something like in the Tesla patent .....with the copper plate in the air.

Yeees, I know an antenna......

No wonder SM was working for years on the TPU. Im somehow sure he saw a lot more but Im not long working with tubes.

Thank you Otto. Does this mean your work with tubes is now concluded?

Hello all,

@AM

this means that I want to continue in my work with tubes. You cant imagine how weird they work.

A time ago I wrote a friend that nobody knows how tubes CAN work. Im sure SM saw also what Im now exploring. And I know that a lot of surprises are waiting for me.

Is this somehow useful for my TPU work? I think yes. Maybe I have "discovered" a new core material. Who knows??

Now dont think I would stop the work on my TPU and waste my time with .... something that has nothing to do with a TPU. First the TPU and then ...

Now I have to wait again for my next 5U4 tube. A month or so.

Otto

Hello Otto,

Would like to mention that this electrolytic capacitor recharging effect happens when you charge up a cap to any voltage then you discharge it: after a certain time the cap regains some voltage all by itself, without any wires connected.
The higher voltage you charge it up the higher the regained voltage will be but this is not linear of course.

This afternoon I charged up a Siemens 150uF 385V DC rated electrolytic cap to 300V from a Variac, then discharged it via a 2kOhm resistor to under 0.1V, then I let the capacitor alone and after about 10 minutes I measured 8.3V across it and after about 30 minutes I measured 10.14V across it. (I used a digital multimeter with 10 MegaOhm inner resistance.)

I can only explain this phenomena as a kind of electret effect inside the dielectric material of the capacitor, as if it would try to rearrange itself to the molecular setup the huge electric field strength (the 300V) earlier caused/arranged in it.

Another member here (nul-points) also reported a voltage regain effect in his capacitor when tested charge transfer in switched capacitors, see here: http://www.overunity.com/index.php?topic=4419.msg99289#msg99289  He used Supercaps in his tests, I used normal electrolytic cap in my test here.

Do you think the effect you have described below is different from what I am referring to now?


Thanks, Gyula

this is called the Casimir effect and the Casimir-Polder force.

it is more noticiable in electrolytic capacitor, because of their dielectric materials interactions.
compression of the dielectric materials under Casimir force and decompression, over time.
ex: oil going back into the paper structure that is separating the plates.

@TheNOP

Thanks for this explanation,  the only missing item from the link is the effect of the DC voltage applied.

So I just did some search since then and found these further explanations:

http://www.rubycon.co.jp/kr/products/alumi/pdf/RecoveryVoltage.pdf   

this mentions space charge polarization taking place in a longer time than atomic / dielectric polarization, this is the cause of the reappearing voltage.

Thanks,  Gyula

EDIT:  further search revealed the effect is called capacitor "soakage" and a very good link is here:

@otto

Just short the capacitor for about 5 minutes, That usually kills them for me and you see not voltage rise. Then connect it to your tube to see if it will rise. I have been trying to find the circuit someone posted, I think it was @wings that put up a ambient energy recovery circuit working with 1 wire input. I built and tested one and it works. I wanted to show it to you because your tube is also a rectifier and this circuit was using four diodes and four capacitors. I am sure the circuit would be useful to know where to add some small capacitor to the tube and see if voltage will rise on his bigger capacitor. But I have looked and looked and cannot find which thread????????

Hello all,

@gyulasun

there is no recharging effect because I have charged this cap the last time at Saturday, shorted it a lot of times and I see always the charging effect. There is nothing to rearrange inside this cap.

But I saw that this works only with my 50 + 50uF/450V cap. Its a big aluminium cap. I tried a lot of other caps without success.

I found the Tesla patent I surched: Utiltzation of Radiant Energy NO. 685 957

I think I have this effect. Maybe I saw this schematic with a detector diode between the plate in the air and the cap??

great lecture !!

An interesting free energy machine using electrostatic fields, which was patented,  was the Hyde motor.   Just like in the lecture, the energy is  1/2 e E^2  x volume between the plates,  and Hyde includes another plate inbetween the existing plates of a capacitor and one of the new two capacitors is used in an external circuit so it can dump it's energy, then the plate that was inserted is removed, and the other original plate still has it's charge on it, and it attracts new charges on the other plate that now is unshielded.   The trick?  removed the middle plate sideways, so his whole assembly is in a rotating sort of an arangment.

anyway, that's what came to mind when I saw this lecture,  made me remember my classes I had in electromagnetics years ago.

QUESTION:

Why use a tube to rectify a silicon rectified voltage?

ANSWER:

Simple, as a highly efficient voltage smoothing device.
Put an AC signal through a bridge and scope it. You will soon see what I am talking about. Noisy DC.

I've been waiting a long time to see that question posed about that SM comment.

Your answer sounds like it may be partially correct. Cleanup of the signal? Probably. I think that statement was more to make us look at the fact that the emissions of the heater are added to the anode and what happens when that goes on.
Voltage of the heater added to the plate.....
Increased velocity ('voltage' if you like) of the circuit current....
